Re: Can you disable the teamspeak?
As of right now on PC you cannot permanently disable voice chat. You can only Toggle Mute on players in the match and for every new player that joins with a mic you have to press the Toggle Mute All again if you wish to do so.
If you have a mic yourself, you cannot disable your mic in game. The only ways this would work is if you had a USB mic or a mic that you could turn off / mute yourself or if you did the following :
Go to the right side if your windows task bar. Right click your sound icon and click on Recording Devices. Click on one of the devices that is not used if you have any, then press Set Default. If you wish to use Skype or any other voice program after doing this, just go to their options and select your mic to make it work with those applications.
If you ever wish to go back to the way it was, use the same steps above but click on your mic you want to use, then click Set Default.
